TRANSFER TRIP SPECIFIC SCL COMMANDS
The SCL commands in this section are specific to the RFL DS-TT Transfer Trip module and are
related to the sequence of events log.
There are three types of occurrences that qualify as “events” in the sequence of events log. These are;
input trip, output trip and alarm conditions. There are three types of alarm conditions; received address
error, CRC error, or ping-pong exceeded preset limit. If any of these events occurrs, it will be entered
into the sequence of events log with a date stamp (month, day, year) and time stamp (hours, minutes,
seconds).
Up to twenty events can be stored in the sequence of events log. Instructions on how to access the
sequence of events log, and how to program the time and date stamp is discussed below.
